Abstract

PROCEDIMIENTO Y APARATO PARA HIDROLIZAR MATERIALES CELULOSICOS O LIGNOCELULOSICOS HUMEDOS, AL OBJETO DE OBTENER AZUCARES MONOMERICOS AL SER TRATADOS CON ACIDO CLORHIDRICO. COMPRENDE LAS SIGUIENTES ETAPAS: PRIMERA, SE IMPREGNA, BAJO ENFRIAMIENTO, LA MASA HUMEDA TRITURADA A HIDROLIZAR, CON CLORURO DE HIDROGENO GASEOSO DE FORMA QUE EL AGUA DE DICHA MASA SE CARGUE CON ACIDO CLORHIDRICO; SEGUNDA, SE CALIENTA LA MASA ASI IMPREGNADA PARA INDUCIR UNA PRIMERA REACCION DE HIDROLISIS, CONVIRTIENDO AL MENOS PARTE DE DICHA MASA EN OLIGOSACARIDOS; TERCERA, SE PROVOCA UN DESPRENDIMIENTO DE PARTE DEL ACIDO CLORHIDRICO EN FORMA DE GAS RECICLABLE; Y POR ULTIMO, SE TRATA LA MASA HIDROLIZADA CON UNA CANTIDAD ADICIONAL DE AGUA Y SE CALIENTA PARA COMPLETAR LA HIDROLISIS, OBTENIENDO UNA SOLUCION DE HEXOSAS Y PENTOSAS.PROCEDURE AND APPARATUS FOR HYDROLYZING WET CELLULOSIC OR LIGNOCELLULOSIC MATERIALS IN ORDER TO OBTAIN MONOMERIC SUGARS WHEN TREATED WITH CHLORHYDRIC ACID. UNDERSTANDS THE FOLLOWING STAGES: FIRST, UNDER COOLING, THE DAMP WHICH IS CRUSHED TO HYDROLYZE, WITH HYDROGEN CHLORIDE GASEOUS SO THAT THE WATER OF SUCH MASS IS CHARGED WITH HYDROCHLORIC ACID; SECOND, THE MASS SO IMPREGNATED IS WARMED TO INDUCE A FIRST REACTION OF HYDROLYSIS, BECOMING AT LEAST PART OF SUCH MASS IN OLIGOSACARIDES; THIRD, A RELEASE OF THE HYDROCHLORIC ACID IN THE FORM OF RECYCLABLE GAS IS CAUSED; AND LASTLY, THE HYDROLYZED MASS IS TREATED WITH AN ADDITIONAL AMOUNT OF WATER AND HEATED TO COMPLETE THE HYDROLYSIS, OBTAINING A SOLUTION OF HEXOSE AND PENTTY.
